The operator is usually a distributor, not a manufacturer
The company whose name is on the casino — the one holding the UKGC licence and running the website — is typically licensing games from outside studios rather than building them in-house. A handful of large gaming groups own multiple casino brands that look distinct on the surface but share the same backend platform, payment processing and much of the same game catalogue underneath.
Game studios: where the actual games come from
Studios like NetEnt, Play'n GO, Pragmatic Play and Microgaming design and build the slot and table games themselves, then licence them to operators. That's why the same slot title often turns up on many unrelated casino brands — it's the same game, supplied by the same studio, just presented through a different operator's website and branding.
Live casino runs on a separate layer again
Live-dealer tables — real dealers on camera, streamed to players in real time — are usually run by specialist providers such as Evolution, rather than by the operator itself. A studio broadcasts from purpose-built facilities, and multiple operators pipe that same stream into their own site, which is why "live casino by Evolution" tends to look and feel consistent across otherwise different brands.
Independent testing sits underneath all of it
Before a game reaches players, testing laboratories independently check that it behaves according to its stated rules and that its random number generator produces genuinely unpredictable outcomes. Certification from a recognised testing lab is one of the conditions operators and studios need to satisfy to keep their licences in good standing.
Why this structure matters as a player
Because the game layer and the operator layer are separate, an operator with a smaller, less established brand can still offer the exact same certified game as a larger one — the game's fairness doesn't depend on how big the front-facing brand is. What does vary by operator is the surrounding experience: game selection curation, app quality, customer support and how clearly bonus terms are written. Those are the differences worth comparing operator to operator, which is exactly what a comparison page like ours is trying to surface.
